This invention relates to improvements in desks and has particularreference to a desk wherein a series of filing trays may be projectedabove the surface of the desk and when not in use depressed within thedesk, thereby eliminating the possibility of an unauthorized personmoving the contents of the trays.

A further object is to produce a device which is simple to operate, neatin appearance and quiet in operation.

A still further object is to produce a device which is economical tomanufacture.

Other objects and advantages will be apparent during the course of thefollowing description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Fig. l is a front elevation of my device with the trays elevated,

Fig. 2 is a side elevation of Fig. l with the trays in depressedposition,

Fig. 3 is a cross sectional view on the line 3-3 of Fig. 1,

Fig. 4 is an end elevation similar to Fig. 1, showing the trays partlyelevated, and

Fig. 5 is an enlarged cross sectional view on the line 5-5 of Fig. 4.

There are many institutions where desks having files positioned thereon,are used. These files must be removed and locked up when the occupant ofthe desk leaves. Or there is always a possibility that an unauthorizedperson may remove some of the contents of the files. Applicant has,therefore, devised a simple arrangement wherein the files may be loweredfrom a point above the top of the desk to a point within the desk.

In the accompanying drawings wherein for the purpose of illustration isshown a preferred embodiment of my invention, and referring particularlyto Fig. 1, the numeral 5 designates the ordinary desk as a whole withinwhich is formed a compartment 6. slidably supported in this compartmentis a cabinet I having trays or draws 8 which may be of any desirednumber. The top of this cabinet is provided with a tray 9. In order tomove this cabinet up and down in the compartment 6 I provide cables IIwhich connect to a follower l2 threadedly engaging a 5 worm l3, which isactuated by a handle M. This worm when rotated causes the follower tomove so as to exert a pull upon the cables which of course pass oversuitable pulleys and are connected to the cabinet. Consequently thecabinet 1 will be raised or lowered depending upon which direction theworm is rotated. When in lowered position the top of the cabinet willentirely conceal thetrays and a person unfamiliar with the same wouldnever suspect the presence of the 15 trays within the desk. The worm ofcourse may be locked if desired so that the same may not be rotatedexcept through the use of a key.

It is to be understood that the form of my invention, herewith shown anddescribed is to go be taken as a preferred example of the same and thatvarious changes relative to the material, size, shape and arrangement ofparts may be resorted to without departing from the spirit of theinvention or scope of the subjoined claims. 25

Having thus described my invention, I claim:

1. In combination with a desk, a compartment formed in said desk and avertically movable cabinet movable into said compartment, and means forelevating said cabinet, said means com- 30 prising cables secured tosaid cabinet and connected to a worm actuated follower whereby when saidworm is rotated in one direction said cabinet will be raised to a pointabove said desk.

2. In combination with a desk, a compartment 35 formed in said desk anda vertically movable cabinet movable into said compartment, means forelevating said cabinet, said means comprising cables secured to saidcabinet and connected to a worm actuated follower, whereby when said 40worm is rotated in one direction said cabinet will be raised to a pointabove said desk, said cabinet having trays slidably mounted therein, anda tray formed upon the top of said cabinet.
